Application filed August 30, 1911. Serial No. 646,950.

To all whom it may concern Be; it known. that l, HENRY B. KEIrER, a citizen of the United States, residing at Lancaster, in the county of Lancaster' and Stale of Pennsylvania, have invented certain new and useful Improvements in Separable Rims, of which the following is a specilication.

.The object of this invention, generally Stated, is to provide a rim for the support of pneumatic or cushion tiros which will he so constructed thatthe tire will be effectually held in place when in use but may be easily and be repaired.

'lhe invention also has for its object the provision of a rim composed of separable members but presenting a continuous unbroken surface for cdutact. with the inner circumference of the tire.

The invention also seeks to minimize the parts necessary to t'orm a complete rim, to simplify the general construction and to lessen the labor of removing or applying the tire.

'lhc objects ol the invention are attained in the use of such a device as is illustrated in the acconipanying` drawings and hereina'tler 'fully described, the novel tentures et the invention being pointed out in the claims at the end ot the description.

ln the annexed drawings, Figure l is a side elevation oil` a wheel equipped with my improved rim, the tire beingy omitted. Fig. 2 is an enlarjfed transverse section on the line 2-2 of l ig. l, aportion o1" the tireI being shown in dotted lines. Fig. 3 is a similarview on the line SH3 of Fig. l. Figa is a similar view on the line 4.4 ot' Fig. l. Fig. 5 is a detail perspectiveview ot' the outer or carrying' member of the rim. Fig. (l is a similar' View of the inner or locking,`

member. Fig. 7 is a detail.longitudinal sec-l tion ol the latch er locking button. Fig. 8 .is an enlarged detail plan view ot the latch. lligs. 9,10 and '1l Aare enlarged transverse sections showing different forms of the rim and `variations in the application of the same to the telly. Fig. '12 is a detail perspectiveview of an alternate form of latch. 13 is a detail sectionalhview ofthe end of the latch shown in Fig. 12,-

lllae hub Ll, the spokes 2, and the telly 3 may be of `the usual or any Apreferred construction. Ait intervals aroundsthe tell are rim-securing devices which "may be or any quickly detached when it is to4 desired forni although l prefer to use, and in Figs. l and 2 have illustrated, a device comprising a shoe et having a pin 5 disposed radially within the telly. The pin 5 is constructed with inciine'jtl or Cain shoulders G which ride upon similar shoulders l7 within a sleeve S' which sleeve may be rotated by means.l of a transversely disposed shaft 9 and suitable intermediate gearing. When the sleeve is rotated, the shoe will he pro-V jected or withdrawn to'scenre or release the rim, and to ell'ect a. holding engagement with therim the 'meeting' su:A ,is ot the shoe and rim are ribbed or corrugated.

'lhe rim constructed in accordance with my present invention conngrises an outer tire-carrying` ring il, the width et' which is approximately equal to the width of the Vfelly and the outer circumferential face of which is uninterrupted thereby yn'oviding` a smooth continuous surface against which the tire may rest without 'any liability of u injury through pinching. On one edge, the

ring' is provnded with an overhangingl tireengaging liange l2 evtending,1 around its entire circumference while on its other edge is an overhanging tire-engaging flange 13 which is mutilated or extends around only a portion of its circumference. @n its in` ner cireumierential face, the ring provided with inwardly projectii'ig` lugs orshort ribs ll which are preferably located adjacent the center of the flange i3 and the purpose of which will presently appear. 'lhe ring also provided in its inner circumferential tace with a stepped or cut out portion at the margin ot' the ring carrying the mutilated flange, and in this stepped portion there is formed a grooveil adapted to be engaged by a'rib or projection 16 on the tire-retaining or locking` member which,

. in the illustrated form of the invention, eon,4

sists of a divided or split spring ring or band 17. This ring` 17 tits within thc stepped portion of the outer ring` 11 with one edge tting against an internal annular shoulder 18 at the inner extremity of said stepped portion and the inner face of the inneror locking or retainer ring is smooth and flush with thel inner circumfer- ,ential face of the outer ringso that the rim :may move easily into position over the periphery of the wheel. The 'ends et the 1nner ring are reduced or notched, as shown at' 19, totithehind thcribs lt and against the ends thereof to prevent accidental separaslightly beveled, as indicated at 2l, so that' theinner ring may be engaged by a screwdriver or other convenient tool to be freed from the outer ring when it is desired to repair the tire. Y

In order to expand the inner ring against the outer ring. and lock it inthe expanded position, I provide a latch which, in the pre Iferredform, consists of a locking button 22 pivotally mounted on the inner circumference of the outer ring'and having its edges grooved or beveled to engage the correspondingly' shaped edges of the division in the inner ring, as shown at Q8. Aspring pin 2l is mounted in the button and yieldably engages a socket in the outer ring when the but-ton is in ylocking position to prevent premature release thereof. convenient form of key may be utilized'to turn the button to releasing position.

The operation of the rim will be readily understood. The tire is placed in position overtlie tire-carrying ring, the tire-retaining member is then locked in position, and the tire inflated. It will be observed that the iange v`13 extends over only about onehalf the circumference of the ring so that throughout its circumference is equal 1n the tire may be easily placed over the ring as it is not necessary to stretch the tire in the manner required by the rims in common use. The tire-retaining member slips into the tire-carrying ring without bearing against the tire and cutting or pinching ot the tire during the tit-ting and locking o the same to the rim is thereby avoided inasmuch-as the tire is' in position on the tirecarrying ring before the retaining member is inserted and the surface of the` said ring Width to the width ot' the tire, The insertion of the locking or retaining member, therefore, causes no Wear on the tire and it slips easily and naturally into engagement with the exposed portion of the elenching bead on the tire. During insertion, the inner ring is slightly compressed in order to clear the lugs I4 and permit the rib I6 to be brought into position to engage the groove I5. After the ring is inserted, it is permitted to expand and the button Q2 is turned so as to fully expand and lock it against the outer ring.. The stress placed upon the rim by the tire will thus be eilectuallyv resisted and the resistance will auto niatically increase as the strain increases.

I do not limitinyself to any particular number or' the grooves l5 andribsl al though'one will ordinarily be sullicient. In

Any

Figs. 9, 10 and 1l, I have shown .modified forms ot the invention in which two of such ribs and grooves are employed.

In order to prevent the rim being pushed too I ar over the wheel, Ivprefer to employ la telly band which extends over the entire periphery of the wheel and is formed with openings at intervals to accommodate the rim-securing devices. The edge of this band nearer the vehicle is turned radially. outward Vto form a stop flange 26l against which the rim will impinge so that the movement thereof laterally over the wheel will be arrested. The band is secured upon the telly ordinarily-by screws'QT inserted radially therethrough into the telly and to brace and support the stop ange 26 I secure clips or brackets QS to the side 'of the felly in position to bear against said ilange as shown, the clips being preferably secured in place by screws 29.

In Fig. 0, I have shown the clip 28 secured by a bolt 3() which extends entirely through the telly, and the elly band, in this instance, is provided with an .inwardly extending flange 31 bearing against the outer side ot' the felly and secured thereto by the said bolt 30. The screws 2) are thus dispensed with and a single series of fastenings utilized to secure both the clips and thc telly band. Y

In Fig. l0, I have shown a rim of the same form as that shown in Fig. 9 but with the felly band secu-red by radial screws as in Fig. 3.

F ig. 1l shows the manner of securing the rim to an ordinary telly. rIlhe inner face ot the rim bears directly against the telly band and the corrugations to engage the shoe shown in Fig. 2 are omitted. telly band is secured tothe telly in any 'preerred manner and to prevent the rim slipping ofi' the telly, the' clips 28 are duplicated on thetwo sides ofthe telly and secured by lbolts extending through the same.

. The form of latch shown in Fig-I2 may be preferred sometimes to the button 22. In this arrangement, the division in the inner or retaining ring or band is an oblique slit 33 so that the ends et the band will overlap and tend tovsupport each other and. beyond but adjacent theends ot' the slit trans i verse lugs 34 are provided on the inner face ot the band. A bail orlever is pivoted at one end in one of the lugs so that it may extend across the slit and bear against the other lug tothereby expand the ring as will be readily understood. i
